FREDERICK (J. WARREN AND WILLIAM H. PRESTON, OF VALLEY JUNCTION, IVISCONSIN.

WRENCH.

Specification of Letters Patent.

Patented Nov. 28, 1905.

To 6L 11/71/0172 it may concern:

Be it known that we, FREDERICK C.WAR- REN and WILLIAM H. PRESTON, residing at Valley Junction, in the county of Monroe and State of lVisconsin, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.

This invention relates to certain new and useful improvements in wrenches, and it particularly seeks to provide a wrench capable of a plurality-0f uses and of a simple construction.

In its generic nature, the invention comprises a longitudinal shank member having a fixed jaw at one end formed, a second shank or handle member having an integrallyformed jaw at one end apertured to receive the first shank member and having the lower portion of the shank grooved to receive the first shank member and designed to form a convenient hand-engaging portion. The movable shank-handle and jaw has an adjustable fulcrum and a fixed-tooth fulcrum for engaging with a rack portion on the firstmentioned shank.

The invention also comprises a pair of separate supplemental jaws adapted to be fitted on the first-mentioned shank and cooperate with the fixed jaw thereof and the movable jaw and having means for firmly attaching them to their respective parts, said supplemental jaws having their engaging faces serrated to be used when the invention is to be used as a pipe-wrench.

In its detailed nature the invention comprises certain novel construction, combination, and arrangement of parts, all of which will be first described in detail and then pointed out in the appended claims; and the invention primarily has for its object to provide a tool of the character above stated, of a very simple and effective construction, in which the parts are so cooperatively arranged and designed as to afford the greatest strength with the least amount of material.

Referring now to the accompanying drawings, in which like numerals of reference indicate like parts in all the figures, Figure 1 is a perspective view of the invention complete with the supplemental jaws attached. Fig. 2 is a similar view with the supplemental jaws removed. Fig. 3 is a vertical longitudinal section of the parts shown in Fig. 1. Fig. 4 is a cross-section on the line 4 4 of Fig. 3 looking in the direction of the arrow. Fig. 5 is a similar view on the line 5 5 of Fig. 3. Fig. 6 is a cross-section on the line 6 6 of Fig. 3. Fig. 7 is a detail perspective view of the fixed jaw and shank. Fig. 8 is a similar view of the movable jaw and handle or shank. Fig. 9 is a detail perspective view of the upper supplemental jaw. Fig. 10 is a similar view of the lower supplemental jaw.

In the drawings, 1 designates the main shank member to which the fixed jaw is 2 attached either by forming the same integrally or by securing the same thereto, and the fixed jaw 2 has a hammer-head 2 and a nutengaging face 2 as shown. The front face of the shank 1 has a rack portion 1 throughout a portion of its length, as shown, and the shank is furthermore provided with grooves 1 1 to reduce the weight thereof, and the said shank 1 terminates in a screw-driver 1 at its lower or free end, as shown.

The sliding jaw 3 is integrally formed with a handle portion 4 and has a rectangular slotway 3 to permit passage of the shank 1, which slotway is provided on its inner face with a rack-engaging tooth 3 as shown. At the rear the jaw 3 has a threaded aperture 3 to receive the adjustable fulcrum 5. The handle member 4 is concaved on its inner face, as at 4*, and provided at its lower end with an overlapping portion 4 for overlapping the shank 1, and the said handle mem ber 4 is also cut away, as at 4 to form a convenient hand engaging or gripping portion for the tool.

When our invention is to be used as an ordinary wrench, it comprises only the parts just before mentioned, and by simply throwing the handle member out in the direction of the arrow in Fig. 3 the same can be disen-- gaged from the rack and adjusted along the shank 1, the jaw 3 having a nut-engaging face 3 to correspond with the nut-engaging face 2 of the fixed jaw 2; but when the invention is to be used as a pipe-wrench the supplemental jaws 6 and 7 are placed into position, as shown in Figs. 1 and 3.

The jaw 6, as shown in detail in Fig. 9, comprise a rectangular member having its upper face provided with a groove 6 to receive the lower face of the jaw 2 and provided with a slot 6* to permit passage of the shank 1, to

' aw, said handle member which it is secured by a set-screw or winged j nut 8, as shown. The under face of the supplemental jaw 6 is provided through about one-half of its length with a pipe-engaging serrating face 6, which merges with a second face 6 111 a plane at an angle to the upper face 6 of the jaw to cooperate with the up i per face 7 of the lower supplemental jaw 7, j which lies in a plane parallel to the plane of j the face 6 and the lower supplemental jaw 7 I has a serrated pipe-engaging face 7 extending in a plane at an angle to that containing the face 7 and at an angle to the lower face 1 7 of the jaw 7. The lower face 7 C of the jaw 7 is countersunk to fit over the jaw 3 and is furthermore provided with a wing 7 through j which a set-screw or wing-bolt 9 passes to secure the supplemental jaw 7 to the jaw 3, as shown. The j aw7 also has an aperture 7 e to permit passage of the shank 1.

From the foregoing it will be seen the invention provides a very simple and effective conl struction of combination-tool combining nut and pipe-wrench, a hammer, and a screwdriver all in one, and the parts are so arranged and designed as to be constructed with the minimum amount of material and the maximum amount of strength. The particular construction of the handle 4, in combination with the shank 1, provides a convenient hand-gripping portion by means of which the tool can be manipulated.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-
